"In the 1930s the docks in Hamburg employed 100,000 people. Now the number is barely 1200, though it is still the 2nd busiest port in Europe, after Rotterdam, with a volume of trade equal to the whole of Austria’s. Until just a couple of weeks before, I could have witnessed the interesting sight of freighters unloading grain from their aft holds and re-depositing it in their forward holds, as a way of extracting additional funds from the ever beneficent EEC. With its flair for grandiose screw-ups, the EEC for years paid special subsidies to shippers for grain that was produced in one part of the Common Market and re-exported from another, so shippers taking a consignment from, say France, to Russia, discovered that they could make a fortune by stopping off at Hamburg en route, and pointlessly unloading the cargo, and reloading it. This little ruse enriched the shippers by a mere $75m before the bureaucrats of the EEC realized that that money could be much better spent on something else - themselves say - and put a stop to the practice."
